Abstract

A printing unit for a rotary printing machine with reversible image setting and digital changeover by means of thermal transfer, having an image-setting unit, an erasing or cleaning component and at least one inking unit. In order to achieve further cost advantages and miniaturization for such a printing unit, in particular for use in small edition colour printing (digital offset press), the form cylinder and blanket cylinder are combined into one cylinder. In order to produce the reversible setting of an image (form production), this cylinder is provided with a hydrophilic surface and interacts directly with an impression cylinder in order to print on a substrate. The image-setting unit and erasing or cleaning component and inking unit are set against this cylinder.
